WARNING:

Disconnect battery negative cable before wiring or service. Devices containing solid state components can be damaged or caused to

malfunction when used in systems which incorporate inductive loads (e.g. relays, solenoids, etc.) that can generate voltage spikes. To reduce the

potential for this type of damage, install a fly back or clamping diode across all inductive loads. Use Murphy diode package 65-00-0343 or equivalent.

A typical diode is 1N4005 and is readily available from commercial sources. Failures of this type are not covered by our Limited Warranty.

IMPORTANT:

To eliminate external interference: RS485(+) and RS485(-) should be twisted pair cable or twist wires together, one twist per

inch minimum. (RS485 wire for example: BELDEN 9841 or 3105A).
